Grey Pneumatic supplies the world's automotive, industrial, assembly, mining, maintenance, construction and energy industries with heavy-duty, high quality impact and specialty sockets. GP sockets and tools are made using the highest quality chrome-molybdenum alloy steel and state-of-the-art manufacturing process and equipment. Through and exact heat treatment, as well as rigid quality control, ensures the correct balance of strength and durability to deliver outstanding performance at the most competitive cost.

• Removable case cover allows bottom to be used as a tool box organizer
• All Duo Sockets are marked by both a roll stamp and a large laser etching on the opposite side, providing readability for a lifetime
• High-quality chrome-molybdenum alloy steel construction with exact heat treatment ensures the correct balance of strength and durability
• High torque drive provides increased strength through the transfer of pressure from the thinnest part of the socket wall toward the thicker section
• A reduction in wall thickness increases socket's capability of being used in tight areas
• Sockets grip the fastener across a broader contact area, reducing the chance of rounding off fasteners
• Increased torque allows up to 20% more torque to be applied than on standard hex impact sockets
